Abstract:

A general theory of flexural and extensional motion of moderately thick laminated composite plates is developed for linear elastic materials and small deformation. Interlaminar stresses are included as independent variables. The effects of shear and rotatory inertia are included. Transverse displacement is assumed to be constant and the in-plane displacements are assumed to vary linearly over the thickness of each layer. Consisten form of boundary conditions is introduced to explicitly include these in the governing function. Gurtin's method is used to transform the partial differential equations into itegro-differential equations. Nonhomogeneous boundary conditions have been explicitly incorporated.
